Application filed J 'une 25,

This invention has to do with an improved construction of extensible buckle or like' article of manufacture. The buckle herein (l]SClOS( l is particularly Intended foruse in connection with belts and theflike, but

it will presently appear that certain "of the features oi? theinvention may also be used to advantage in connection with buckles or extensible devices for other purposes than Nevertheless, in view of the fact'that One of the objects of'the invention is to provide an extensible 'buc'kle,the "two sections whereof are spring connected together so that they tend to tele'scope, the one into the other, under spring tension thus placing a tension on the belt. In this connection it" is an object to provide a construction making use preferably of a single winding drum operated by a'sing'le spiral spring.

Another object of'the invention is to provide means forlimiting the extension'movement of the two parts with respect to each other so as to avoid any excessive strain being' imposed onthe spring'and drum mechanism.

Another object of the invention is to provide a very simple construct1on,one Which can be manufactured from a very small numthey will not become readily disconnected or jammed or'otherwise' disar'ran'ged.

Other objects and uses "of the invention will appear from a detailed description of the same which consistsin the features of construction andcombinations of partshereinafter explained.

of a belt buckle embodying the features of the present invention, the attached belt ends Fig. 3 looking in the direction of the all-9W8;

to telescope in and out,

her of parts, one which'is'so arranged that the parts can be very easily assembled; and one such that when "theparts are assembled In the drawings Fig. 1 shows a face view Fig. 4 shows a section on the line 4-4 of i926. ""seriar No. 118,509.

Fig. 5shows a section on the line 55 of Fig. 3 looking irrtlie direction of the arrows; and Y F ig. 6shows a detailed face View of the d r'i'im, looking'into the open side thereof, the pivot stud beingin place but the spring beremoved.

Thedevice herein disclosed includes a pair 'of telescoping box-like structures 7 and 8 respectively. These are substantially rectangular in face view as shown in Fig 1, but

they are preferably curved on a radius of substantially 8"1nches when viewed from aiboveas in F ig. 2. Inasmuch as both ofthe telescoping members are formed on the same radius of their central planes they may readily'slipwith respect toeach other so as Theouter end of the outer member 7 is closed as shown at 9 andthe outer end of the inner member 8 is closed as shown at 10. Both ofthe inner ends of the members are open; and the top and bottom walls 11 and 12 of the outermember receive the top and bottom walls 13 and 14 of the inner member with a nice fit. Likewise,the back and front walls 15 and 16 of the outer member receive the back and front walls 17' and '18 of the inner member with a nice fit.

Aloop 19'has its ends extended through openingsin the end wall 10 of the inner meniber" and then hooked over as shown at "20 and 21. This'loop receivesthe end portion 22 of one end of the belt'23; and said portion may be led back and then "connected in an adjusted position bymeans of a snapper 24'which issnapp'ed ontothe selected "companion snapper member 25. In'this way the length of the belt is easily adjusted.

The other end 26 of the belt is preferably provided with a series of ho1es'27, a selected one ofwvhich" may be hooked over a hook 128 which projects from'the back wall 15 of "'the'other companion telescoping member at a;point"close to its end wall 9.

There is formed in the wall 17 of themner member 8 a rectangular hole which receives the squared end 30 of a stud 31. This stud is of proper length to work freely between the baek and front walls 15 and 16 of the outer member 7 so that said stud can not become disengaged from the rectangular hole of the inner member 8. Preferably also the front wall 18 of the inner member is slotted as shown zit/32 in Fig, 5 so as to facilitate setting the stud into place.

A hollow drum rotatably mounted upon the stud. This drum includes a floor together with an encircling flange 35 projecting upwardly from said floor. A pin 36 projects from the stud 31 at a point about midway of the might of the flange 35 as shown in Fig. 8 in particular; and a notch 37 formed in the floor 34 of the drum permits said drum to be set down over the stud when the parts are being assembled.

lhe notch 38 is formed in the flange as shown in Fig. 6. A spiral spring 39 has its inner end perforated and set down over the pin 36. The outer end 40 of said spring is provided with a hook, and said hook is in turn hooked over one side of the slotted opening 38 of the flange 35. By this construction the tension of the spring is exerted between the drum and the stud, and the stud itself is non-rotatably carried by the inner housing member 8.

A small, very flexible metal cable 41 has its inner end 42 soldered or otherwise permanently secured to the drum flange. The other end of said cable is provided with a small eyelet 43 which can be hooked over a pin 44 which reaches inwards from the back wall 15 of the outer member 7.

Preferably this pin 44 comprises an ex tension of the hook 28 already referred to.

Examination of Figs. 4 and 5 in particular will show the presence of a recess 45 cut backwards into the end of the back wall 17 of the inner member 8. This is to allow free movement of the parts without interference from the pin 44.

In order to prevent the two housing members from being separated an excessive amount I have provided a longitudinal slot 46 in the bottom wall 14 of the inner member 8, said slot receiving a pin 47 which projects thereinto from the bottom wall 12 of the outer member 7.

While I have herein shown and described only a single embodiment of the features of my present invention, still I do not intend to limit myself thereto except as I may do so in the claims.

I claim:

1. As a new article of manufacture an extensible buckle or the like comprising in combination a pair of elescoping members both of which are substantially rectangular in cross section, said members having open telescoping ends, both of said members being formed on a cylindrical curvature of substantially 8 inches in radius, a stud nonrotatably secured to one cylindrical face of the inner member and projecting through the opposite cylindrical face thereof into contact with the inner surface of the adjacent face of the other member, a drum rotatably mounted on said stud, a spiral spring secured to said stud and to the drum and tend ing to wind up the drum, a flexible tension member having one end secured to the drum on which it winds, a loop on the other end of the tension member, a pin se cured to a cylindrical wall of the outside telescoping member and receiving said loop, a pin and slot connection between tv-xo of the walls of the telescoping members serving to limitthe opening movement of said members with respect to each other, and suitable belt attaching devices on the extreme ends of two telescoping members substantially as described.

2. As a new article of manufacture an extensible buckle or the like comprising in combination a pair of telescoping members of rectangular cross section and broader in one cross sectional direct-ion than the other, a stud secured to the inner telescoping member and extending across same, a drum pivotally mounted on said stud, a spiral spring having its ends connected to the stud and to the drum, a flexible tension member having one end connected to the drum and its other end connected to the other telescoping member, and suitable belt connecting devices in conjuction with the extreme ends of the two telescoping members substantially as described.

3. As a new article of manufacture an extensible buckle or the like comprising in combination a pair of telescoping lnen'ibers of rectangular cross section, said members being broader in one cross sectional direction than the other, and said members being formed on a cylindrically curved surface, a drum pivotally mounted within the inner member on an axis extending transversely across said member, a spiral spring within said drum tending to retract the same and wind it up, and a flexible tension member having one end connected to the drum and the other end connected to the other telescoping n'ien'ibcr, and suitable connectors for attachment of a garment to the two telescoping inemacrs substantially as described.
